VAPOR-BURNER."

SPECIFICATION forming part of Letters Patent No. 252,631, dated January 24, 1882.

Application filed OctoberlS), 1881. (N0 model.)

ingcham her and generator, for the purpose of a rapid and economical generation of gas or vapor-for consumption in the heating-chamber. The said pipes also form tubular supports for the said chamber and auxiliary generators.

For a more full and complete description of the said invention reference will be had to the following specifications, and to the anmxed diawings, making part of the same.

Figure l is a front view, partially broken away to show the interior of the heating-pipes, generator, and combustion-chamber. Fig. 2 is atop view with dome or cap removed. Fig. 3 is a side view with the cap or dome removed.

Like letters of reference refer to like parts in the several views.

The principal object of this improvement is to produce a burner having the qualities nrcessary for a rapid and economical generation of .vapor or gas for heating purposes, its construction being simple and readily manipulated.

The dome or cap A, Fig. 1, is perforated, as seen at a a, which dome is mounted upon a base-plate, B, Figs. 2 and 3. This plate is attached to the lugs G O, projecting from the tubes D D. In the central part of the baseplate is a boss, E, with a central opening, F, in which is inserted a tube, G, extending into the chamber H, Fig. 1. The pipe Gr may be screwed into the opening or bore If, so as to be adjustable, as may be required in the efficiency of the burner.

Connected with the lower end of the tubes D D is the vapor or gas generator I, which is in open communication with said tubes, as seen in Fig. 1. This generator is connected to the supply-pipe J, through which passes the rod.

K, provided with a needle-valve, L, at the upper end, while the lower end is provided with the ordinary device for operating it. The pipe J is connected in the usual way with the oilreservoir. These parts are not shown, as they maybe the same as those in common use and arranged in the same way in relation to the burner.

The tubes D D are closed at the upper ends and are designed for a threefold purpose.

cham be are vent-holes c 0, Figs. 1 and 2, which cause a flame from the chamber H to be impinged upon the tubes ator near the points I) b. This heat is quickly transmitted to the generator I through the passage of the tubes and their substance, the tubes to a certain extent forming auxiliary generators to the generator I, as more or less oil and vapor will pass into the bore of the tubes. Hence the heat taken up by the tubes is quickly transmitted .to the generator I for the conversion of the hydrccarbon oil into vapor for heating the chamber H, as supplied through the needle-valve. This arrangement presents a large and quick generating capacity, so much required in this class of heaters, and at the same time is economical in this, by the fluid not being forced in a partial or quite unvaporized state into the combustion-chamber.

To obtain the best results from gasoline in vapor-burners, it should be highly vaporized and consumed under a high degree of heat. In this way there is more economy of the fluid or oil, and a greater degree of heat generated, than the same quantity of fluid used in ordinary vapor-burners of this class.

For the purpose of preventing the flame-jets issuing from the vent-holes c 0, Figs. 1 and 2, from being deflected from the tubes the shields M M, Figs. 1 and 3, are extended down from the under side of the base and spread out lat- "erally from the tubes, as seen in Fig. 3, by which the ventsc c are between the tubes and shieldsM M, as seen in Fig. 1, which causes the flame-jets to-be concentrated upon said tubes for the purpose, described.

Directly below the needle-valve is a dripcup, N, into which the gasoline runs on open i ment with the needle-valve and leading into [0 ing said valve for igniting the burner in the the said combustionchamber, substautiallyas ordinary Way. set forth, and for the purpose specified.
